Re: The lights under the my Sharp Carousel Microwave oven...
We see (and repair) this
a lot. The problem is on the control panel, which
we regularly repair nationwide by mail for $39.95 postpaid in about a
our Web site, you can get details of our service, plus we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
This light failure often
occurs when a bulb goes out and the filament
shorts, or when the bulbs are removed or installed without first
unplugging the oven from the power line. Either can cause such a
failure on the controller.
This can often also
affect the exhaust fan operation, too. The lights and fan can be
inoperable or stuck on too.
Feel free to contact me directly (and please remind me of your
full model number) for more information & help.
happy to help you with free advice and we'd appreciate your

Changing the light bulb on your Sharp carousel microwave will allow you to have needed light inside the oven. Microwaves are not designed for consumers to change the light bulb due to manufacturer liability, but it can be done. Following the proper steps will ensure a successful installation.
Unplug the Sharp carousel microwave from the electrical outlet.
Locate the screws around the outer cover of the Sharp carousel microwave and unscrew all the screws.
Lift off the covering.
Locate the bulb and unscrew. Screw in your new bulb.
Replace the cover and screw back tightly. Once done, test your new bulb.
There are a couple of safety thermostats in the oven to shut down power if something overheats. One is on the magnetron tube (the microwave source), the other is on the cooking cavity. These sometimes go bad. There's also a power line fuse that may have failed, or become loose in its mounting clips. These can be tested with an ohmmeter; they should all measure very close to zero ohms if they're good.
Another possibility is that the control circuit board in the oven may have failed. I have worked on several Sharp ovens where the power transformer for the board has gone bad for no good reason. If the board goes bad the oven may appear to be dead as well.
Microwave servicing is best left to professionals. If you're thinking of keeping this one, take it to a service shop (or call for home service) and get an estimate. Then decide whether to repair or replace.
Hope this has helped a little. Thanks for using Fixya!
Hello there To replace the light you will first have to remove the outer shell. To do this (1). Remove all of the screws on the back of the microwave that hold on the shell (2) Remove the screws that are on the bottom.
(3) now the shell should slide off towards the back of the microvave. Note : this may take a little bit of pressure to get it off ok?
(4) Once the cover is off look towards the fromt of the microwave and you will see the bulb. now just replace the bulb and reinsert the cover and the screws and you are all done ok? pretty easy ha/ best regards michael
Are you talking about the light inside the microwave? The front vent I think will allow you to get to the bulb. Should be a couple of small scrrews holding the vent cover on, remove them take vent off. Start it up again and see if the light bulb wiring or socket is arcing

Microwave_svc's site is awesome! I was able to get all the help I needed for a similar Sharp Carousel microwave. My bulb was simply loose in the socket base causing intermittent bulb lighting. Microwave_svc's helpful links got me to the service manual and, along with a nice set of "tamper-proof" screw compatible TORX bits I bought at HarborFreight, I was easily able to get cover off, remove bulb socket, tighten bulb, re-install bulb socket, button unit back up, and, voila, the light now works without intermittent blinking.
